5 support or axis to assume a closedor open position. I V

, The object of the present invention'is to generally improve andsimplify the construction and operation of window mountings of thecharacter described; to provide amounting which permits the sashes toswing about a vertical axis which constantly changes position as thesashes areopened or closed; ,amounting which is connected both to theupper and lower rails of the sashes, thereby forming a substantiallyrigid connection between the sashes and the casing or frames;

1a mountingwhich is simple in construction,

easy to install, and which is completely hidden between the sashes andthe frames when the sashes are closed, and as'such protects I themountings against rain and weather 7 action; a mounting which permitscomplete reversal of the sashes, thus permitting ready cleaning of bothexteriorand interior surfaces of a window when necessary; and further,to provide meansfor lockingthe win dows when in openposition.

One form which my invention may assume is-ez'cemplified in the followingdescription and illustrated in the accompanying drawings, in which- VFig. 1 is a central vertical section of a window and easing showing theapplication of the invention.

and the head 2 of the casing is a mounting.

such as shown in Fig. 3, and disposed between the sill 3' and the lowerrail of the window sash is a mountingsuch as shown n Fig. 2. t

The mounting shown in Fig. 2 consists of a metal plate B which extendsfrom end to end of the sill. The plate consists of abase portion 5 atrack or channelledportion 6, and a front lip or flangewZ, the platebeing secured to the sill by screws or other means and as such isstationary. The sill isv recessed to receive the plate B and the innersection ofthe sill indicated at 8 is extended av slight distance overthe sill to cover and a 1,711,921 PATENT OFFICE.

enclose the track portion 6. The lower rail 1 of the sash is similarlyrecessed as shown, at 9 and thus covers or encloses the arms and guideshoes hereinafter to be referred to, thus protecting the same againstrain and weather action; that is, by recessing the rail as shown at 9 afront lip 10 is formed and all parts of the mounting are thusenclosedand covered when the window is closed.

, Slidably mounted on the plate B is a shoe generally indicated at 11;this shoe being rail of the sash and the sash or window .will

thus swing in unison with the hinge-arm 1 1 when sliding movementisimparted to the shoe 11. A secondarm is also employedas indicated at15; this armbeing pivotally attached. to the plate B as indicated at 16at one end and it is similarly pivotally attached to the outer end ofthe hinge-arm .14

as indicated at 17. The upper mounting is somewhat similar to the lowermounting; 1

that'is, the head 2 is channelled to receive a channel-shaped track suchas indicated at 18; this being secured in the head by screws orothermeans- A hinge-arm 14; is secured to the upper rail of the sash anda second arm' 15 is pivotally secured at one end to a plate 19, and itsopposite end is pivotally secured to thehinge-arm 14 as indicated at17*. Theinner end of the hinge-arm 14: is provided with a pin'20 andthis extends upwardly into the channelshaped track 18 andis guidedthereby. The upper rail of "the sash is recessed for the purpose ofconcealing the arms 14 and 15 when thesash is in closed positionf Fromthe foregoing description it should be understood that the arms 14 and14 are rigidly secured to the upper and lower rails of the sash and thatthe sash or window is thus free to' swing about a constantly changingvertical axis when moved to open position or vice versa when closed;that is, one end of the sash is stabilized by the arms 15 and 15, whilethe other end of the window is supported and guided by the shoe 11 andthe pin 18.

If when standing inside of a room one pushes outwardly on. the left handside of the window, it is obvious that the shoe 11 and the pin 18 willmove along their tracks towards the left hand side of the casing andthat the hinge-arms 14 and 14 will assume a right angular position withrelation to r the sill and head when the window is comportance as itpermits ready cleaning of both sides of the window without resorting tothe usual practice of leaning out when washing and cleaning the same.The same is true when the sash opens from the right hand side as theequipment is applicable for sash opening either on the right or leftside.

' By referring to Fig; 2 it will be noted that the outer face of thetrack portion 6 is provided with a series of notches or recesses such asindicated at 25, and that a latch or bolt 26 is mounted on the shoe 11,which 7 may be moved into or out of engagement with the notches 25 bymeans of a pivotally mounted lever 27. This is also of considerableimportance as it permits locking of the 1 window in a number of openpositions, thus preventing slamming or closing of the win dow if itshould happen to be stormy, windy or otherwise- The latch or bolt 26which is disposed transversely of the rail 6 is mounted on and. carriedby one arm of the latch lever 27 -disposed longitudinally of the railand pivoted intermediate of its ends to the" triangular shoe to form twoarms, the bolt being mounted on one arm and the other arm being providedwith an upwardly extending terminal operating portion. One of the lugs12 of the shoe forms an abutment for the latch bolt when the latter isengaged with one of the notches 25 of the lower track.

By referring to Figs. 4 and 5, a slightly modified form of the structureis shown; that is, the track indicated at C is only extended slightlybeyond one-half the length of the sill and there stopped. This type ofmounting is employed where a semi-reversible window is desired; that is,the window can be swung. from closed position to complete open position,but it cannot be completely reversed as shown in Fig. 6. The mounting isotherwise practically identical; that is, arms 15 and 14 are employed,but the slidingshoe tween the window casing and the sash, and

that the mountings employed are completely enclosed. and protectedagainst rain and weather when the sash or window is closed.

It can furthermore be seen that the mechanism or mounting employed isexceedingly simple, cheap to manufacture, and easy to install, and thata standard form of casing and sash construction maybe employed;

the only change required being the recessing of the head'and sill andthe upper and lower rails of the sash as previously stated.

When a mounting such as shown in Figs. 1, 2 and 3, is employed, completereversal of the window is permitted, thus facilitating washing of thewindows and eliminatingall i danger in connection therewith, and wherecomplete reversal is not required, the mountings shown in Figs. 4 and 5may be employed. Even with such a mounting it isfairly easy to wash thewindows as both sides can be readily reached without excessive leaningout of the window.

' In connection with the "semi -reversible type of mounting, I wishit'understoodthat this may be employed in connection with transoms,horizontally swinging windows, awnincr or projector type windows, andthe like. Tn such cases the guide rails and arms are secured to thesides of the casing or door frame and the transom or window may thus beswung about a horizontal axis.

Having'thus described my invention, what I claim and desire to secure byLetters Patent is In combination, a window frame, a sash,

and having upwardly extending lugs'entirely channel and provided at oneend with 10 spaced apart and engaged With the channel an operatingportion, and a'latch bolt carried interiorly thereof to provide a twopoint by the other end of said lever and disposed bearing, said shoebeing pivoted to the other transversely of the track and adapted to ofsaid pair of hinge arms, means for securengage said notches, one of thelugs forming ing the sash to the hinge arm, which is an abutment for thebolt and the latch lever 15 slidably connected to the channel, a latchand'bolt being concealed b the sash When 7 lever pivoted intermediate ofits ends to the the latter is in its closed position.
